Faster and cleaner panel profile nesting tooling

Advanced tools with tungsten alloy head and precision ground steel shank for high speed and cleaner CNC nesting allows furniture makers to optimise sheet material and reduce wastage.

PCD tooling specialist Cruing (UK) is to unveil two new advanced tools for high speed and cleaner CNC nesting With extensive experience of producing nesting tools, such as the Pilot range, Cruing has developed Nexus and Aerotech as part of Nesting+, an advanced technology tooling programme.

Nexus combines two components to produce a high productivity full speed single operation nesting tool.

It allows furniture manufacturers to increase the optimisation of sheet material and reduce wastage.

Nexus has a highly resistant tungsten alloy head and precision ground steel shank.

The parts are positioned, interconnected and locked together using the patent 'Q-Lock' system.

With only a 12mm minimum diameter, cutting resistance is reduced allowing feed speeds of up to 20m/min plus without strain on the electro-spindle.

Because the tungsten alloy head is an excellent heat conductor, operational-related heat is conducted away from the sheet material and brazed PCD tips.

Longer tool life is achieved as the use of tungsten alloy allows Nexus to withstand intensive mechanical stress, far more than steel.

This guarantees the same high performance after each service cycle.

The Aerotech nesting tool is designed to assist the CNC machining centre's dust extraction system by removing MDF dust and residual material from the nested grooves during operation.

The efficiency of Aerotech depends on the feed speed and machine speed rpm parameters.

Total dust removal is generally achieved at 18,000 rev/min at 15m/min feed and 24,000 rev/min at 20m/min feed.

This reduces or eliminates post-operation dust residue, delivering a cleaner and healthier working environment.

Aerotech provides single operation high speed nesting up to 15m/min-plus.

In addition, cutting pressure is reduced, causing less strain on the electro-spindle, saving on energy costs and reducing operational-related heat.

In certain circumstances its use makes it unnecessary to have larger, more expensive extraction systems, including compressed air blowers to move compacted dust from the grooves.

Furniture manufacturers with low efficiency, or elderly, dust extraction plants can optimise their existing extraction with Aerotech.

Nexus and Aerotech techniques can be combined in a single tool if required.

Said Cruing (UK) co-director, Trevor Barnes: "Nesting, optimising the number of components that can be produced per sheet of material, is becoming increasingly popular with furniture manufacturers.

It is a demanding application for CNC tooling which places above-average strains on the tools and requires specific design and construction techniques." He explained: "Standard profiled routers are unable to withstand the additional stress generated while nesting.

Common CNC tools can force the machine to default to a lower feed speed and complete the nesting sequence in two operations; pre-cut and separation and finish." Barnes continued: "Our new long-lasting Nesting+ system represents a major technical breakthrough that overcomes all these problems and delivers faster and cleaner nesting." Also on the Cruing stand will be numerous examples from the Italian-made range of diamond tools for the woodworking and furniture industries.

They include tools for panel sizing machines, panel squaring machines and edge banding machines, CNC machining centres, point-to-point machines and post-forming operations.

They can be used with a variety of materials, are resharpenable for a long working life and give low noise emission.

Cruing technical staff will be on hand throughout the exhibition to answer questions and provide advice on how to obtain a better end product and reduce tooling costs.
